SALMON JONES AND GEORGE B. MARSHALL, OF CINCINNATI, OHIO.

SMOKE-CONSUMER.

SPECIFICATION forming part of Letters Patent No. 263,708, dated September 51, 1882.

Application filed May 15, ieee. (No model.)

To all whom it may concern:

Be it known that we, SALMON JONES and GEORGE B. MARSHALL, otOincinnati, in the county of Hamilton and State of Ohio, have invented a new and useful Improvement in Smoke-Consumers, which improvement is fully set forth in the following specification and accompanying drawings, in which- Figure l is a front view of a furnace equipped with our improved smoke-consuming `device. Fig. 2 is a side view, partly in section. Fig. 3 is a perspective view of portion of the pipe; Fig. 4, one of the sections of the pipe containing the discharge-nozzles.

The object of our invention is to provide a 'smoke-consuming device; and it consists in providing the flre-box or combustion chamber with a transverse pipe, made in sections located at a point directly under the boiler, at the forward end,sa"1d pipe being provided with two lines of discharge-nozzles, one line projecting directly back from the pipe, and the other line projecting downward and backward by means of elbows, so that the air expelled from these nozzles will be discharged at points directly above and at thesides of the furnace-doors, as will now be fully described in detail.

In the accompanying drawings, AA represent the boilers, and B the combustion-chamber, constructed and arranged in the ordinary manner. The sidewalls andthe bridge for the combustion-chamber require no change to apply this device.

C C represent the furnace-doors.

D is a transverse pipe, which runs across the top of the boilers at the foward end; and E E represent vertical pipes leading from the transverse pipe at each end, so that they pass down by the side of the walls, but are not set into the walls.

F is a vertical pipe, also leading from the l pipe D between the boilers.

G represents a transverse pipe, formed of sections H I. This sectional pipeis connected with the vertical pipes E F, and extends transversely across within the combustion-chamber at the forward end, directly above-the line of the furnace'doors. rIhe central vertical pipe Fsupports the middle of the horizontal pipe G, as well as to serve for supplying said pipe in part with air. The transverse pipe G is composed of sections H I, the section H having external screw-threads at each end,

which are adapted to screw into the sections I, containinggthe internal screw-threads, L, at each end. Each alternate section I is provided with a discharge pipe or nozzle, J, which nozzle projects directly back from the section, so that the air, when expelled, is on a horizontal plane with the -pipe G. The other alternate sections I have pipes or nozzles K, which project downwardand rearwardly in the forni of an elbow, so that the air expelled therefrom will be forced to the rear of the combustionchamber on a plane below the line of the pipe G. The sections are so graduated in length that oneor more of the rearwardly-projecting nozzles J will be directly above the furnacedoors O, and one or more of the downturned elbow-nozzles will be by the sides ofthe doors.

M represents a `pipe connected with the l transverse pipe I) above, and this pipe M leads from a fan or blower, N, located in the engine-room, or by the side of the boiler, or in any suitable place. A valve, M', located at any suitable point, O, may be used to turn off the air from the blower when not needed.

The operaton is as follows: The blower is set in motion, and air is expelled through the pipes and nozzles into the combustionechann,

ber directly'above the burning fuel, thus providing the mass with a steady supply of oxygen. The verticgl pipes E F should beexposed as much as possible to the heat of the furnace, so that the air within will be heated, or partially so, before being expelled. We find that the higher the temperature of the discharged air the more perfect the combustion.

Having described our invention, what wc claim isi In smoke-consumers, the horizontal transverse pipe G, formed of the separable sections H I, each alternate section having the rearwardly-projecting horizontally-disposed nozzle J, and the other alternate section having the downwardly-projecting elbow-nozzle K, substantially as and Vfor the purpose shown.

In testimony that we claim the foregoing we have hereunto set onr'hands this l13th day.

,of May, 1882, in the presence of witnesses.
